While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

PWM pins are generally used in controlling output devices in Arduino projects. To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

To ensure that the head unit buttons still work in conjunction with the steering wheel buttons, the Arduino would have to keep the pins as inputs until a steering wheel button was pushed, the pin ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino.

Adding USB functionality to your Arduino projects used to be a pain, but thankfully, the V-USB project came along and gave your ATMEGA328 the ability to control the USB lines directly and mimic ...

Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
